Disclosed herein are novel linear copolymers having weight average molecular weight of 500 - 30,000 and comprising structural units represented by the following formulae (I), (II), (III) and (IV):
wherein R₁, R₂ and R₃ mean individually an alkyl group having 4 or fewer carbon atoms and R₄ denotes an alkyl, cycloalkyl, aralkyl or phenyl group, and multivalent metal salts thereof in each of which the multivalent metal forms the multivalent metal salt between carboxyl groups within the same molecule of the copolymer or between different molecules of the copolymer; color-developing agents comprising multivalent metal-modified resins of the copolymers; and color-developing sheets obtained by coating the color-developing agents on their surfaces.
An epoxy-resin composition comprising (A) an at least bifunctional epoxy compound and/or an at least bifunctional epoxy resin, (B) a curing agent, and (C) an accelerating agent, the accelerating agent essentially containing a phosphine oxide represented by general formula (1);
where R1 to R6 all of which may be the same or not are hydrogen, straight, branched or cyclic alkyl having 1 to 10 carbons or aryl or aralkyl having 6 to 10 carbons. The epoxy-resin composition can be used for sealing a semiconductor integrated circuit in the manufacture of a semiconductor device.
